Abstract (en)

Disclosed are an air duct assembly and a fan heater applying in the air duct assembly which includes a volute tongue positioned in the volute forms a air duct with the volute. The air duct is configured with an air inlet and an air outlet. A cross-flow wind turbine positioned in the air duct introduce the airflow into the air duct from the air inlet, and blow out the airflow in the air duct through the air outlet. The volute includes a first volute tongue member, the volute tongue includes a second volute tongue member, which are respectively located at the two sides of the air inlet. And the size of the angle between the line connecting the root portion M of the first volute tongue member to the axis O of the cross-flow wind turbine and the line connecting the root portion N of the second volute tongue member to the axis O of the cross-flow wind turbine on the same cross-section is from 110° to 170°.
